Fabrication of g-C3N4/Ag/CoFe1.95Eu0.05O4 heterojunctions with enhanced photocatalytic degradation activity

We prepared g-C3N4/Ag/CoFe1.95Eu0.05O4 heterojunctions resulting in the effective visible-light absorption and promoted separation of photogenerated electron hole pairs. The kinetic constants of Z-type heterojunctions gC3N4/Ag/CoFe1.95Eu0.05O4 for the degradation of methyl orange were 7.01 and 9.18 times higher than that of gC3N4/Ag/CoFe1.95Eu0.05O4 and g-C3N4, respectively. Our work provides a new strategy to deal with the organic pollution by photocatalytic degradation.

Automated summary

We prepared g-C3N4/Ag/CoFe1.95Eu0.05O4 heterojunctions that effectively absorbed visible light and efficiently separated photogenerated electron-hole pairs. The kinetic constants of the Z-type heterojunctions gC3N4/Ag/CoFe1.95Eu0.05O4 in the degradation of methyl orange were significantly higher than those of gC3N4/Ag/CoFe1.95Eu0.05O4 and g-C3N4, indicating its potential in photocatalytic degradation of organic pollutants.
